## Homework Statement

A cargo ship carrying 50 tons of coffee is initially traveling North with a speed of 40 m/s. Five minutes later, the cargo ship is traveling at 20 m/s into san Fransico bay in a direction 48 degress North of East. Use a coordinate system with + x corresponding to East and +y corresponding to North to answer the following question

a) What are the x and y components of the initial velocity?

B) what are the x and y componenets of the final velocity?

C) What is the change in velocity (magnitude and direction) of the ship?

D) explain the difference b/w velocity and speed?

## Homework Equations

a) No clue

B) cos0=a/h

sin0= o/h

C) delta (r)/delta(t) and to get delta r i use c^2= B^2 + C^2

## The Attempt at a Solution

a) x=0 y= 40 m/s

B)

C)

If i have the equations right i don't know what to use for o and a
